i386.md (expsf2, [...]): New patterns to implement exp, expf and expl built-ins as inline x87 intrinsics.
* config/i386/i386.md (expsf2, expdf2, expxf2): New patterns to
implement exp, expf and expl built-ins as inline x87 intrinsics.
(UNSPEC_FSCALE, UNSPEC_FRNDINT, UNSPEC_F2XM1): New unspecs to
represent x87's fscale, frndint and f2xm1 insns respectively.
(*fscale_sfxf3, *fscale_dfxf3, *fscale_xf3): New insn patterns
to encode x87's "fscale" instruction followed by a pop.
(*frndintxf2): New insn pattern for "frndint".
(*f2xm1xf2): New insn pattern for "f2xm1".
* reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_FRNDINT and
UNSPEC_F2XM1 like UNSPEC_{SIN,COS} and handle UNSPEC_FSCALE like
UNSPEC_FPATAN.
* gcc.dg/builtins-22.c: New test case.
* gcc.dg/i386-387-1.c: Update to test exp.
* gcc.dg/i386-387-2.c: Likewise.
